13 Claims.

This invention relates to a talking machine and concerns itself with astructure that is adapted to be placed in the body of a doll forproducing a talking doll. More specifically the invention concernsitself with a machine of this character which can be set in operationfrom without the body of the doll and which automatically stops when arecord has been exhausted and which will elevate and return the stylusto its initial position without requiring any manu al manipulation.

The invention comprises the novel structure and combination of partshereinafter described and more particularly pointed out and defined inthe appended claims.

In the accompanying a preferred form of this drawings which illustrateinvention, and in which similar reference numerals refer to similarfeatures in the different views:

Figure 1 looking in In describing the invention with reference to thedrawings, it will be noted is supported by a pair of side plates 1 plate2 which bridges the side plates.

be observed that a shaft ring to Figure 3, it will that the mechanismand a top In refer- 3 is journalled for rotation'between the sideplates 1. A spur gear 4 is keyed upon the shaft 3 adjacent one sideplate. This gear 4 is adapted to be rotated by a reciprocating rack bar5 which is slidably mounted in a guide casing 6 which may be secured orwelded to the adjacent side wall 1.

A bearing strip '7 is preferab top of the housing face for the top ofciprocating movement.

the rack ly positioned in the to form a good bearing surbar 5 during itsre- The front end of the guide casing 6 terminates in a downwardlyextending flange 8 which form s a shoulder that is adapted to be engagedby a shoulder 9 (Figure 5) on the rack bar 5. It will be noted that therack bar 5 terminates at its front end in a handle member of reducedportions whereby the shoulder 9 is formed. The handle portion of therack bar embodies a knob with a collar 5a which is adapted to abut thefront end of the casing whereby the reciprocating movements of the rackbar 5 is limited to a predetermined movement.

Reverting to Figure 3 again it will be observed that a hub member 10 iskeyed upon the shaft 3. This hub member 10 has a ribbon spring 11secured thereto and wound thereon with the free end thereof anchored toa rod 12 that connects the side walls 1. It might be mentioned that thisribbon spring serves as a spring motor for actuating the drivingmechanism as will later more fully appear. The hub 10 of the springmotor terminates in a flanged ratchet wheel 13. Adjacent the ratchetwheel 13 there is a large spur gear 14 which is loosely journalled uponthe shaft 3 and is provided with a pawl 15 that engages the ratchetwheel 13. A spring 16 normally urges the pawl 15 into engagement withthe ratchet wheel 13. The large spur gear 14 which is driven from thespring motor through the instrumentality of the ratchet wheel 13 andpawl 15 is adapted for driving a small spur gear 17 keyed upon a shaft18 which is journalled between one of the side walls 1 and an L-shapedbracket 19 which is secured to the same side wall.

A spur gear 20 is secured upon the shaft 18 and this gear 20 meshes witha pinion 21 secured upon a shaft 22 journalled between the side walls 1.The shaft 22 carries a gear 23 which in turn carries a small pinion 24secured upon a governor shaft 25 upon which a suitable governor 26 ismounted.

Reverting again to Figure 3. it will be seen that a sleeve member 2'? isloosely journalled upon the shaft 3 adjacent the hub 10. This sleeveterminates in a pinion 28 which meshes with the spur gear 20 and isdriven thereby relative to the shaft 3. The sleeve 2'? which may betermed a sleeve shaft carries a record drum or cylinder 29 upon which asuitable record 30 may be carried.

The manner of supporting the stylus that cooperates with the record willnow be explained. It will be observed that a cylindrical rod 31 extendsinwardly from one side wall 1. A U- shaped member 32 is journalled uponthe rod 31 by means of a pair of bearing lugs 33 which extend inparallel relation from one leg of the U-shaped member. A hangar 3 1which is provided with a pair of parallel arms terminating in pintleportions journalled in the arms of the U-shaped member 32 forms thestylus bar. The stylus bar 34 comprises a pair of forwardly extendingarms 36 which approach each other at their outer ends and between theouter ends thereof, the holder 37 for the stylus pin 38 is pivotallymounted. In referring to Figure '7 which shows one of the arms 36 brokenaway, it will be noted that the holder 37'has a tail portion 37a whichextends beyond the pivot 39 of the holder. This tail portion 37a extendsbetween the two arms 35. A coil spring 40 connects the tail portion ofthe holder with an arm 41 extending outwardly from the U-shaped member32. A vibration conducting wire or the like 42 also conmeets the tail ofthe holder 37 with a. diaphragm,

43 which is suitably mounted'in a head 34 supported upon the top plate 2of the frame of the machine.

The mechanism for elevating the stylus bar and returning the same to'mitial position as soon as a record has been played'will now be setforth.

With reference to Flgure'3 it Zwillbe observed that 25 acolla'r 45 issecured upon one end of the shaft 3 and this collar carries an arm 46which termimates in a right angle portion 47'that extends over theperipheral face of the record drum. Re-

" ferring to Figure 4, it will be seen that the portion 47 is in theform of a channel that slopes inwardly. The aforementioned stylus bar34has a depending lug 48 which is normally located in the path ofmovement of the arm portion When the spring motor iswoimdup by pushingthe rack bar. 5 inwardly,'the shaft 3 will be rotated and will rotatethe arm 46 into the position shown in Figure 7. When the rack bar 5 isreleased and the record cylinder is rotated through the instriunentalityof the spring motor,

the shaft '3 will be rotated in a reverse direction until the arm 46rotates to the position shown in Fig. 2, and this will occur when thestylus has traversed the'complete cylinder. At this point the inclinedportion 47 of the arm will engage the lug 48 and elevate the stylus barfrom the record cylinder, and as soon as this stylus bar is elevated, itwill slide along the inclined face of the portion 47 to the oppositeside of the a record cylinder, that is, to its initial starting position. To prevent thestylus from dropping oif the outer edge of therecord drum, astop lug 49 has been stamped from thecasing.

While it appears that the operation of the machine should be clearlyunderstood from the foregoing description, a brief summary of theoperation will be set forth. In its normal position, the motor isunwound and it is necessary to wind the spring 11 before it willoperate. The spring motor is adapted to be wound up by pushing the rackbar 5 inwardly until the collar 5a strikes the casing, whereby theshaft3 will be rotated for Winding up the spring 11, and the arm 46 will berotated to its starting position as shown in Fig. 7. During thisoperation, the ratchet wheel 13 will ride idly over the pawl 15 withoutrotating the gear 14. However, as soon as the inward pressure upon therack bar 5 is released the spring motor will operate the gear 14 throughthe instrumentality of the pawl l5 and ratchet 13. The gear 14 willrotate the shaft 18 which is geared to the governor shaft as previouslyset rotation.

stylus pin will of course gradually traverse the same, and the arm 46will gradually rotate with the shaft 3 as it is rotated by spring 11 ina direction reverse to that required to Wind the same. Until it engagesthe lug 48 on the stylus bar and elevates the same and causes the sameto slide over the sloping face on the angled portion 47 to its initialstarting position. It will of course be understood that the U-shapedmember 32 supports the stylus arm for rotatable and swinging movement inorder that it may be actuated by the control arm 46 in the manner setforth. When the stylus has completely traversed the record cylinder therack bar will of course have movedoutwardly until the shoulder 9 engagesthe shoulder 8 on the casing to prevent further It will therefore beobvious that the reverse rotation of the shaft 3 will return the rackbar 5 outwardly into position for again winding up the spring motor.
